This paper presents a novel quasi-Z-source based bidirectional DC/DC converter consisting of a quasi-Z-source inverter, high-frequency transformer, and current-fed push-pull converter. Both inputs provide buck/boost functionality by incorporating shoot-through states. Moreover, it has high reliability due to an elimination of dead time and utilization of shoot-through state. Operating principles and modulation techniques are presented.
